Bad after service on new Exter.

We have bought a Exter and we told the sales person there is water marks on the windscrean front of the vehicle. There was a chip on the back door. A new vehicle not a demo or a second hand car. Well after alot of phone calls it was in to get it cleaned up. The front have still got water marks. The polish is all over the black rubber and the chip is still not repaired. Do not take or sign anything before the deffects are repaired. I am not happy with the service. And becarefull for a sales person if they promise that it will befixed.
